Steering device for use in solar tracking equipment

Abstract

A steering device for use in solar tracking equipment includes: a fixed base (10); a rotary base (20) correspondingly connected to the fixed base (10) and provided with a worm gear (22); and a driving module (30) disposed in the fixed base (10) and including a worm unit (33) and an adjustment mechanism (34), the worm unit (33) includes a cylindrical body (331) and a worm (332) supported in the cylindrical body (331), and the cylindrical body (331) is pivoted in the fixed base (10), the adjustment mechanism (34) is disposed corresponding to the cylindrical body (331) for adjusting the swinging motion of the cylindrical body (331), thereby enabling the worm (332) and the worm gear (22) to be mutually engaged. Accordingly, the backlash between the worm and the worm gear is able to be adjusted thereby enhancing the rotation precision.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a steering device, especially to a steering device for use in solar tracking equipment.[0003]2. Description of Related Art[0004]With the trend of developing various types of alternative energy, a solar panel is the most popular for generating electricity, and advantages of green power, low pollution and no noise are provided. Thus, the solar related power generating technology has been widely applied and promoted in recent years. For effectively increasing the time period allowing the solar panel to be operated and increasing the amount of generated electricity, a solar tracking equipment is assembled with the solar panel for meeting different sunlight radiating directions in different seasons. However, there are some shortages to be overcome in the existed solar tracking equipment. As such, the present invention is aimed to overcome the shortages.[0005]A conventional steering device for...

AI Technical Summary

Benefits of technology

[0007]The present invention is to provide a steering device for use in solar tracking equipment, in which the backlash between a worm and a worm gear is adjustable for enhancing the rotation precision.

[0008]Accordingly, the present invention provides a steering device for use in solar tracking equipment, which includes a fixed base, a rotary base and a driving module; the rotary base is correspondingly connected to the fixed base and provided with a worm gear; the driving module is disposed in the fixed base and includes a worm unit and an adjustment mechanism, the worm unit includes a cylindrical body and a worm supported in the cylindrical body, and the cylindrical body is pivoted in the fixed base; the adjustment mechanism is disposed corresponding to the cylindrical body for adjusting the swinging motion of the cylindrical body, thereby enabling the worm and the worm gear to be mutually engaged.

[0009]Advantages achieved by the present invention are as following: with the installation of the adjustment mechanism, each component made by casting is able to be assembled without being processed with a precise mechanical treatment, thereby lowering the cost for mechanical process and having more flexibilities for arranging the fabrication procedure; through disposing the worm gear in the internal space of a tubular body, the worm gear is able to be effectively prevented from being adhered with dusts or debris existed in the nearby environment, thereby ensuring the transmission stability of the worm and the worm gear and also prolonging the service life of the steering device; by installing U-shaped shaft seats in a case member, the assembly / disassembly of convex shafts or convex shafts and bearings can be facilitated, thereby providing more conveniences in assembly; with the installation of an axial adjustment mechanism, the worm is able to be axially displaced for adjustment, thereby no backlash being generated between the worm and the worm gear; and through installing the driving module is a space defined by the case member and a cover member, the maintenance or replacement for electric components can be facilitated.

Problems solved by technology

However, there are some shortages to be overcome in the existed solar tracking equipment.

However, there still are some problems happened when the conventional steering device for use in solar tracking equipment is operated, because the location relation of the worm and the worm gear is fixed, components such as the worm gear and the carrying plate have to be precisely fabricated with a mechanical process for allowing an adequate engagement between the worm and the worm gear, so the cost for fabricating and processing are relatively high.

In addition, the solar tracking equipment is mostly installed in the outdoors, With the ever changing environmental conditions such as wind blowing, sunlight radiating and rain falling, components such as the worm and the worm gear may be deteriorated, thereby causing the steering unable to be processed or the steering not being precise.
